✨ NAME ✨

vmw_sou_crtc_mode_set_nofb — the one that's gonna create a new screen for you 🎀

🌸 SYNOPSIS 🌸

void vmw_sou_crtc_mode_set_nofb (struct drm_crtc *crtc );

🦋 ARGUMENTS 🦋

⭐ DESCRIPTION ⭐

So here's the vibe: this function creates/destroys a screen. That's the whole job, she does both, she's versatile, we stan 👑

And the best part? this function cannot fail ✨ which is genuinely iconic of her. BUT — and listen, bestie, this is the important bit 🙈 — if somehow we do run into a failure, it just does the best we can to get out. No drama, no return code, no nothing. She simply leaves 🚪💨

lowkey that's the whole safety net. there is no plan B, there's just "do the best we can" and honestly? relatable 😭
